Koe wa Tetsu (Live), video thumbnail

The lights change and the guitars drop lower. Hikari gives the signal, and "Koe wa Tetsu" opens the Steel Side of the concert.

A voice that does not break. A voice that carries every scar. A voice strong enough to open the way forward.

Five breaths. Five voices. One sound of steel.

Everyone, it's time for our steel side.
